Salivary amylase, yav tas los hu ua ptyalinis, cov piam thaj-polymer cleavage enzyme uas yog tsim los ntawm cov qog ua kua qaub, rhuav cov hmoov txhuv nplej siab rau hauv m altose thiab isom altose. … Amylase zom cov hmoov txhuv nplej siab rau hauv me me molecules, thaum kawg yielding m altose, uas nyob rau hauv lem yog cleaved rau hauv ob lub qabzib molecules los ntawm m altase.
Dab tsi yog qhov cuam tshuam ntawm qhov kub thiab txias ntawm salivary amylase kev ua haujlwm?
Thaum qhov kub thiab txias, cov enzyme salivary amylase yog deactivated thiab nyob rau ntawm qhov kub thiab txias, enzyme yog denaturated. Yog li ntawd, ntau lub sij hawm yuav raug coj los ntawm enzyme los zom cov hmoov txhuv nplej siab ntawm qhov kub thiab txias. Ntawm 37 ° C, enzyme yog qhov nquag tshaj plaws, yog li, siv sijhawm tsawg dua los zom cov hmoov txhuv nplej siab.
Kev ua haujlwm ntawm salivary amylase Class 10 yog dab tsi?
Cov qaub ncaug amylase yog ib qho enzyme uas muaj nyob hauv cov qaub ncaug ntawm tib neeg thiab tsiaj txhu. Lub luag haujlwm ntawm salivary amylase yog hloov cov hmoov txhuv nplej siab rau hauv suab thaj. Qhov no enzyme pab hauv kev zom zaub mov. Thaum lub sij hawm zom cov hmoov txhuv nplej siab, amylopectin thiab amylose tau tawg thiab hloov mus rau hauv m altose.
PH zoo tshaj rau kev ua ntawm salivary amylase yog dab tsi?
Salivary α-amylase muaj qhov ua haujlwm luv luv. Qhov tseeb, nws tau nqos nrog cov khoom noj zom thiab tom qab ntawd tsis ua haujlwm los ntawm pH ntawm plab tsis tshua muaj; Amylase qhov tseeb muaj qhov pom zoo pH ncig 7, thiab pH ntawm qaub ncaug feem ntau ntawm 6.4 thiab7.0.
PH ua li cas amylase denature?
Zoo tias ntawm pH > 11, amylase yuav tsis ua raws li nws qhov kev ua tau zoo. Qhov zoo tshaj pH rau alpha-Amylase yog 6.9 - 7.0. Deviation nyob rau hauv no ntau yam yuav hloov lub functionality ntawm amylase thiab huab alkaline mob (hais pH 11, raws li tau hais los ntawm Mr. Sivamani) yuav ua kom tiav denaturation.
